Six ridiculously over-the-top superyacht features

Helipads and cinemas are par for the course on the world’s most amazing superyachts but behind the tinted glass and sleek white exteriors lie fantastic, fun and ludicrously extravagant features most of us wouldn’t even dream existed.

We’ve dug around to find the most lavish and outlandish elements of these incredible vessels – just to give some insights into this world of luxury and indulgence within the world’s most impressive gleaming superyachts.

Your own leisure submarine!

Superyacht: Eclipse

Fancy some underwater fun? On board the Motor Yacht Eclipse is a ‘mini leisure submarine’ that can dive to a depth of 150 ft – ideal for scenic underwater trips for you and a couple of guests, who might be able to spot sea turtles and dolphins while sipping champagne… Russian billionaire Roman Abramovich is the owner of this big beauty – worth over $1billion - which can reportedly accommodate 36 guests and cater for up to 70 crew members. There's even thought to be an anti-paparazzi shield of lasers that sweep the surroundings and a German-built missile defense system.

Concert Hall for a 50-piece orchestra

superyacht: Al Said

If music is the food of love, this is surely the tastiest yacht of all! The 155 m Al Said belongs to Sultan Qaboos of Oman, and amazingly, is rumoured to house a concert hall large enough for a 50 piece orchestra. This is the perfect place to for a floating orchestral extravaganza! The yacht was custom built in 2008 by Lurssen Yachts in Bremen and was designed to accommodate 70 guests and up to 154 crew, with a maximum speed of 25 knots. With an eye-popping value of $300 million, this vessel truly belongs in this list of the most expensive boats on the planet.

Fully equipped hospital

Superyacht: The Prince Abdulaziz

This enormous vessel is the Royal Yacht for King Abdullah of Saudia Arabia, so perhaps a fully equipped on board hospital – not to mention a mosque and a cinema – makes perfect sense. It would certainly make sea sickness easier to bear when the waters are choppy! This 147m yacht was built in 1984 by the Danish yard Helsingor Vaerft and is manned by a crew of 65.

Fairytale glass staircase

Superyacht: Dubai

It’s the world’s second largest private yacht, and within is a truly spectacular piece of interior design. On board guests can descend a stunning staircase featuring glass steps which change colour, creating different moods and light effects. This blends beautifully with the luxurious interior design throughout the superyacht. Owned by Sheikh Mohammed Bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, motor yacht Dubai was jointly built by German ship builders Blohm + Voss and Lurssen. Boasting seven decks, Dubai also features a beautiful mosaic swimming pool, Jacuzzis and a helipad.

Gym designed by Usain Bolt

Superyacht: Quattroelle

No excuses for getting yourself into shape on here! Onboard the fabulous yacht Quattroelle - whose name aptly means love, life, freedom and luxury - you will find a gym designed by none other than Olympic sprinter Usain Bolt. The 88-metre-long Quattroelle, built by Lürssen and Moran Yacht & Ship, and designed by Nuvolari-Lenard, also features five decks, a and full spa with hair salon, a massage room, several pools, and a helipad. You can invite 16 guests and you’ll be looked after by staff in 8 staterooms. The current owner of the superyacht is supposedly Jamaican born Michael Lee-Chin.If you fancy a holiday on the Quattroelle, it is available for charter for about $1 million a week.

Mega yacht Christina O became famous once bought and converted by the legendary Greek shipping magnate Aristotle Onassis in 1954, and is said to embody his love of opulence, luxury and indulgence. Here you find a very famous swimming pool whose floor is a replication of the ancient mosaic of Knossos. Even better - it converts to a dance floor located on the main deck. Other amenities onboard Christina O include theGalaxy Bar, show lounge, library, beauty salon, children’s playroom, fitness centre.

In her heyday the Christina O played host to the likes of Sir Winston Churchill, John F.Kennedy, Marilyn Monroe, Elizabeth Taylor and John Wayne. As actor Richard Burton put it: “I do not believe that any man or woman in the world would resist the temptation and the pure narcissism shamelessly flaunted on this boat.”
